12/10/12 Shutter Speed


Today we used shutter speed in order to capture moving objects and avoid motion blur.
In the image to the left we can see that the moving object (Jack) isn't touching the ground as he has jumped, but the image is not blurry. For this image the shutter speed was set to about 1/250th of a second which is used roughly to capture people as they aren't that fast moving.

In this image we can see that the object is walking but we have avoided motion blur by using the shutter speed. Again I used 1/250th of a second to capture this image.

To capture the object moving in this image I used 1/500th of a second. Because Jack was moving quicker by running rather than walking to avoid motion blur we had to increase the shutter speed to capture his image.

In today's lesson about shutter speed I learnt that 1/60th of a second is the slowest you can go without motion blur. To avoid shakey or blurry images a use of a tripod should keep the camera still and therefore capture a clean image of the object you are photographing. A person walking works out at about 3mph and that means that using 1/250th of a second will capture the image, whilst running works out at about 10mph and therefore using 1/500th of a second will catch the slightly faster moving object without motion blur.
The shutter is just used to capture light.


In order to capture the light in this image, Becky had the camera set to TV with 1/30th of a second which lasts for 30 seconds. Below are some other images of Becky that I took using shutter speed set at 1/30th of a second. As well as shutter speed, we used the flash to take these images as well.


In order to improve on these images I think more practise using different settings on the shutter speed could improve my images giving the subject more time to create something with the light.
